Parker 325HB-8-6PP Barbed Male Connector 1/2 in Barb 3/8 Npt

Product Description

The PARKER 325HB-8-6PP is a single-barb male connector designed to join flexible tubing to a 3/8 inch NPT male-threaded port. Molded from polypropylene and finished in black, this fitting accepts tubing with a 1/2 inch inside diameter and a 0.55 inch outside diameter. It is rated to a maximum working pressure of 125 psi and handles temperatures from 0 degrees F up to 212 degrees F, making it suitable for a wide range of fluid-handling and low-pressure pneumatic applications. The fitting meets FDA Compliant and NSF/ANSI 51 standards, qualifying it for use in food-equipment and potable-water-contact environments. Licensed plumbers, HVAC technicians, and equipment service techs are the typical installers.

This connector is commonly used in light commercial and residential fluid-handling systems where flexible tubing must terminate at a threaded port. Typical applications include ice machine water lines, beverage dispensing equipment, water treatment systems, and HVAC condensate or water-feed lines. The polypropylene construction resists many common chemicals and mild acids encountered in these service environments. Its compact overall length of 1.6 inches suits tight equipment enclosures where clearance is limited.

Compatibility

Designed as a standard replacement or new-installation male connector for flexible tubing systems using 1/2 inch ID tubing and 3/8 inch NPT threaded ports in plumbing, HVAC, and food-service equipment applications.

Installation Notes

Installation is typically performed by a licensed plumber or qualified HVAC technician. Shut off the water supply and relieve system pressure before removing any existing fitting. Apply thread sealant tape or compound to the NPT male threads in accordance with applicable IPC or local plumbing code requirements. Slide the tubing fully onto the barb and secure with an appropriate clamp rated for the operating pressure of the system.
